What is stereo?

There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

Omniray®
Horn is the distinguishing feature of all Zingali's creations assuring the
utmost quality in sound reproduction. It is the most notable element of the
enclosure and the company's pride.

The horn
history at Zingali starts in the 80's with a traditional bi-radial model in
wood, the forerunner of what would become the emblem of the company. It was
used in the 8800 Studio Monitor line. Since the release of the first line of
studio monitors Giuseppe Zingali kept on with his research in the field of horn
acoustics trying to improve the quality of mid-high frequencies reproduction.
He has analyzed the conventional circular exponential horn whose axial length
is greater than its maximum diameter. Being its drawbacks like causing
colorations and beaming effect in the high frequencies well known, Giuseppe
Zingali tried to improve the sound emission by optimizing horn shape and
proportions through numerous calculations and tests. The studies were concluded
in 1995 and the idea that became the future of the company was the circular
wooden horn of a particular shape now patented worldwide as Omniray
®Technology. The horn is carved of a solid piece of Yellow Poplar. Its curve
characteristics and throat depth guarantee the most accurate reproduction of
medium-high frequencies available today. The circular shape of the horn allows
360° radiation of sound with an angle of dispersion of up to 140°. The horn
curve is not fully exponential but consists of parts described by specific
formulas. Each part is “responsible” for the quality of reproduction of a
certain frequency range. Together with the relatively short throat depth this
allows to balance frequencies in the region from 500 Hz to 20 kHz within the
limits of ± 1.5 dB.

When you
look at a Zingali loudspeaker, its hand crafted wooden cabinet and the wooden
horn in particular, you can't but think it's a kind of musical instrument.
Traditionally many musical instruments are made of wood that normally is the
key to the magic sound of a piano, a violin or a lute. Things have not changed
since the times when these instruments were created. No matter how far the
technology goes, a piano rim made of anything different from wood just has no
sense. The Zingali loudspeakers are “alive” thanks to such a noble material as
wood and natural colors of coating that emphasize its charm.

Omniray®
Technology unites in harmony the geometry, materials and dedication of a true
audio enthusiast to assure outstanding sensitivity of loudspeakers, improved
dynamics and sound transparency. The optimum horn shape provides enough
efficiency typical for horns but without distortions. Thanks to their
sensitivity our loudspeakers can be matched perfectly even with low power valve
amplifiers. They deliver striking clearness of sound and articulation even on
low volume. The sound is detailed and true to the original no matter what
musical genre you prefer. The typical characteristics of Zingali loudspeakers
is the effect of performer's presence in the room be it voice or an orchestra.

Without question the Model 10B is the most advanced instrument of its kind today. This is the Tuner that was rated by Hi/Fi Stereo Review (December, 1965 issue) as " ... we have neverseen a tuner to compare with it ... so outstanding that it is literally in a class by itself." Marantz engineers have bypassed the inherent limitations of conventional circuits through the employment of bold new concepts and highly sophisticated electronic techniques. The performance of every circuit stage shows the dramatic order of improvement which can be achieved through creative inventiveness.

Now, with the introduction of the Marantz 10B, all the requirements for real high fidelity reception have been met. FM reception with the Model 10B, is comparable in every degree with the clarity and fidelity normally found only in stereo tapes and discs.

Performance properties of the 10B in regard to quieting, stereo separation and distortion are without precedent. Its combination of high sensitivity, ultra-sharp selectivity, fast quieting action and reduced susceptibility to multipath effects, ensures exceptional results in fringe area. While the advanced features and performance specifications appeal to the primarily technically inclined, the Model10B's simplicity of operation attracts the listener who is simply a lover of good music. In whatever case, the extent of the new high standard established by this fine instrument is recognized by all of critical judgement.

RF Section

The precision tuning capacitor has a "Linear frequency" characteristic so that station calibrations appear evenly and accurately spaced along a full 10" tuning dial. RF stages are balanced-tuned throughout. An important feature is the radar-type, balanced-bridge diode mixer.

IF Section

The unique Marantz IF circuit is based on the development of an "18-pole" phase-linear. The ideal characteristic of the filter passband permit performance improvements which are unobtainable with conventional coupled circuits. Phase-linearity in the 200 kc passband eliminates a major source of high-frequency distortion and loss of separation 108 dB/octave cutoff slopes make the Model 10B the most selective FM tuner in existence. The strongest signals have no deteriorating effect on its ideal passband characteristics. IF alignment is permanent, being unaffected by tube changes or normal aging.

Limiters and Discriminator

There are 9 limiters in the Model 10B using matched pairs of silicon planar diodes. Each IF stage is self-limiting, preventing overload on stronge signals, and eliminating the usual need for AGC circuits. Quieting on weak signals is close to the theoretical threshold, with ultimate quieting well in excess of 70 dB. The discriminator circuit is extremely linear, ensuring low distortion through the subchannel range.

Multiplex

The highly sophisticated Marantz circuit permits the inclusion of phase correction to maintain proper phase-amplitude relationships. This allows the use of an extremely effective SCA rejection filter witout the usual loss of separation at high frequencies. Separation is well in excess of 30 dB to 15 kc. The output filter circuit provides very sharp attenuation of residual sub-channel components above the audio range, eliminating noise and interference from SCA. Precision-gapped ferrite cup-cores or precision toroidal coils are used for all filters. Automatic stereo switching and inter-channel muting are both accomplished by means of ingenious electronically triggered photo-electric circuits.

Multipath- Tuning Indicator

In March 1962, Marantz introduced the concept of using an oscilloscope tube as a multipath and tuning indicator in the early prototypes of the Model 10. As each station is tuned, its correct center position on the passband is clearly displayed. Simultaneously, the presence of multipath becomes visible, making it quite easy to readjust the antenna for best results. A panel switch permits test display of the left and right FM channels, or external signals from tape recorders, discs, etc.

Marantz deliberately withheld its entry into solid state products until it was possible to step into the position of leadership in this field. Now, Marantz engineers have develpoed new methods of solid state application to produce a circuit design equalling the matchless performance and dependabilility of the previously unmatched Marantz designed vacum tube 7C preamplifier.The new Model 7T delivers unequalled specifications for low noise and low distortion, without the usual transistor problem of inadequate signal handling capacity or dynamic range. The widest dynamics excursions on your favorite record or tape will not overload the sensitive low-level phono stages.This has not been possible in previous solid state equipment, since the quietest operation of a transistor is the very condition under which it will produce clipping and distortion with normal input signals. Marantz solid state circuitry now has solved this problem, and traditionally impeccable performance is assured in the new Marantz Model 7T Solid State Stereo Preamplifier.

Since the introduction of stereo discs, achieving the total signal of a stereo record and maximum channel separation has been a problem with conventional tracking tone arms. Marantz has solved that problem with the new SLT-12 Straight Line Tracking Turntable.

When the master disc is cut in the recording studio, the cutting head travels across the disc in a straight line. The grooves are cut proportionately to the volume of the sound; as the sound ebbs, the grooves narrow - as the sound swells, they broaden. Each side of the groove carries a separate track - one for each stereo channel. These grooves carry the total sound originally recorded.

The Marantz SLT-12 tone-arm tracks acrossthe disc in a straight line following the path originally created by the cutting head. Thus the stylus always tangent to the grooves, receives the full signal incised on each side of the groove. It is the only system available which faithfully reproduces the sound that was priginally recorded.

The critical elements of the Marantz SLT-12 Turntable provide maximum precision and atability in support of the tone-arm assembly. The free-floating stylus is always fully positioned in the groove by counter-balancing the tone-arm assembly. A 12 lb. cast and dynamically balanced turntable rests upon a massive, precision-ground tungsten carbide thrust bearing to produce low friction, dimensional stability. Power is derived from ahysteresis-synchronous motor. The precision-ground uscothane drive belt is noted for its uniquely stable elasticity. Push-button controls have been installed for convenience, while the cueing device eliminates the necessity of ever touching the tone-arm.

The SLT-12 system includes stereo cartridge with elliptical diamond stylus and walnut base.

The only turntable system designed to precede the state of the art. Advances in cartridge development yet-to-come will obsolete most existing tone-arms. only the Marantz SLT-12 has the capacity to accommodate all future developments.

The LT-30 is a late mode linear tracking design, thus containing all the advanced technology for tracking precision. It tracks the record precisely as the original masters are cut; in perfect tangency with the groove for the absolute minimum distortion. The LT-30, also known as the Diatone LT-3, was introduced in 1980 as the pinnacle of Mitsubishi ‘s Linear Tracking turntables. The goal of every linear tracking turntable is to mimic the position of the cutting head as was during the master cut, yet few can track as precisely as the LT-30. Straight-line tracking completely eliminates the problems of tracking error and stylus overhang. Anti-Skating correction is unnecessary because the system exerts no skating force. External forces acting on the stylus are in complete balance. Further, the tangential arm is much lighter than conventional arms, since it is much shorter. For these reasons, the LT-30 transliterates records with unprecedented clarity and amazing sonic accuracy. Some other features of the LT-30 includeFully Automatic Operation -Just press play and the arm is set into motion into the lead in groove. It returns to arm rest when the end of the record is reached. Controls are provided to advance the tonearm in either direction as well as pickup/set down.Auto Record Size Detection -Size of record is automatically detected and correct speed is set. Speed can be manually changed at any time.Multiple Tonearm Adjustments -Tracking force, tracking angle, tonearm height, stylus height are all user adjustableRepeat Feature -this feature allows play of the same record repeatedly.Tracking Error Indicators -a 3 light display shows when optimal tracking is achieved

The Klipsch Belle was originally introduced in 1971 and today it is considered the queen of the Klipsch heritage line. It is the only speaker system Paul Klipsch designed with a woman in mind, his wife whom he named the speaker after. As the story goes, Belle Klipsch wanted a less obtrusive, pleasing to the eye speaker system for their living room, yet without compromising the trademark Klipsch sound. Starting with the enclosure design of the famed La Scala system, Paul Klipsch tweaked the proportions of cabinet to give it a more balanced look and “beautified” it with grille cloth and high-grade veneer. Of course Belle couldn’t have been more pleased with the results, not to mention the thousands of wives thereafter. The Belle has a truly timeless esthetic appeal that seems to get even better with age.While the Belle Klipsch has been called the most beautiful heritage speaker system of all time, not many were sold. It is pretty much sonically identical to the La Scala system, which was priced approximately 55% lower (85% lower if you settled for a pair of unfinished Scalas) then the Belles. Because the buying demographic of Klipsch speakers was predominantly men, most of which weren’t concerned with style, you can understand why paying a premium for beauty was not appealing. Ironically, today, of all the Klipsch Heritage systems, the Belle has seen the biggest increase in value because there are relatively so few around.K-77-M High Frequency Driver/HornThe famed compression driver /horn tweeter gives you vivid, sparkling high frequency detail beyond the range of audibility. You hear a sharply focused, lifelike stereo image. Dynamic range is breathtaking. Distortion is nowhere to be heard. K-55-V Alnico Mid Range Driver/Exponential Metal HornMidrange frequencies are the most critical to your enjoyment of music. In the Belle, these frequencies are capably handled by a powerful, smooth sounding compression driver/horn assembly. This midrange driver assists the Belle, in delivering an amazing 104 decibels of sound pressure when operating on just one watt of input power. This results in awesome dynamic range and distortion free response. K-33 WooferThe K-33 fully takes advantage of it folded bass horn cabinet. Deep full-bodied bass that is not only heard but felt!Type AA CrossoverThe passive crossover network of the Belle, is a vital component to the overall performance of the system and is a classic example of the KLIPSCH dedication to engineering excellence. This network takes incoming electrical information and assigns it to the proper driver to achieve the smoothest frequency response.

Unmatched CraftsmanshipKLIPSCH cabinetry is the immediately evident indicator of the construction quality that has made KLIPSCH famous. Meticulously crafted by the finest craftsman in the business. Each pair is precisely matched for color and grain structure. One tiny flaw in one speaker and the pair is destroyed. The cabinet of the Belle, is also critical to its bass response since a large part of this cabinet forms the woofer horn.Belle Folded Bass HornThe Belle’s folded horn woofer has long been the marvel of audio enthusiasts and engineers alike. The horn has always been the most efficient means of reproducing sound. But for deep bass, a horn of considerable length is required. KLIPSCH long ago solved this problem by "folding" a horn into a more compact size, resulting in unmatched bass reproduction.

Sony has been the leader in both professional and home digital audio for over a decade. With such breakthroughs as PCM processors, Compact Disc Players and Digtal Audio Tape recorders. Now, the Sony ES engineerss, a dedicated group who are above the compromise between technology, convenience and price, have created the ES Series.

The TA-N77ES:

Apower amplifier worthy of the Sony ES name.

Even the most advanced components require superior amplifier performance. The TA-N77ES deliveres 200 watts of continuous power per channel into 8 ohms and has the operating stability to deliver 660 watts ofdynamic power into a 1 ohm load.

A Spontaneous Twin Drive design with separate voltage and current stages helps reduce cross-interference. And the oversized power transformer and high-current non-switching discrete output stage provide additional power on demand.

In may of 1983, Kyocera introduced a CD player with true 16-bit digital filters. Today, the competition's calling this circuit "the latest thing". Years ago we had four-times oversampling. This year every high-end player worth mentioning has a similar design. In september, 1984 Kyocera raised some eyebrows with the world's first Fine Ceramics anti-resonant CD chassis. Now the stores are full of flimsy imitations.

How did all these innovations happen to come from Kyocera, and not some household name? perhaps because kyocera's knowledge of digital circuitry comes fromyears of building computers for some of the best-known names in electronics. perhaps because Kyocera is a world leader in Fine Ceramics, the technology used to house circuitry in aerospace and other advanced applications. Or perhaps beacouse some top-rated CD players form other brands were actually made by Kyocera.

Now Kyocera has four world-beating Compact Disc Players, ranging in suggested retail price from $ 350 to the $800 model DA-710CX shown here.Each boasts technology so advanced, it's a preview of what the competition will be selling in 1989. After all, history does repeat itself.
